The provided Google Apps Script code contains two functions: COST_PER_ITEM and getDiscount. These functions work together to calculate the cost of an item based on its quantity, price, and an optional coupon code that may offer a discount. Here’s a detailed description of how these functions work:
1. COST_PER_ITEM(item, quantity, price, couponCode, discountTable) Function:
This function calculates the cost of an item, taking into account its quantity, price, and any applicable discounts provided through a coupon code. Here’s a breakdown of its functionality:
- item: This parameter seems to be unused in the function, so it’s not impacting the calculation of the cost.
- quantity: The quantity of the item you want to purchase.
- price: The unit price of the item.
- couponCode: An optional parameter that represents a coupon code. If a valid coupon code is provided, the function checks for discounts in the discountTable.
- discountTable: An array that stores coupon codes and their corresponding discounts. The array is a two-dimensional array, where each sub-array contains a coupon code in the first element and the associated discount percentage in the second element.
The function proceeds as follows:
- It calls the getDiscount function to check if a valid discount is available for the given couponCode in the discountTable.
- The discount variable is assigned the discount percentage obtained from the getDiscount function.
- It calculates the initial cost of the items (quantity * price).
- The cost is adjusted by subtracting the discount percentage from it (cost – cost * discount). If no valid discount is available, the discount percentage is 0, so the cost remains unchanged.
- Finally, the function returns the calculated cost after taking any discounts into account.
2. getDiscount(couponCode, discountTable) Function:
This function is responsible for looking up the discount associated with a given couponCode in the discountTable. Here’s how it works:
- couponCode: The coupon code for which you want to find the discount.
- discountTable: The array that stores coupon codes and their corresponding discounts.
The function proceeds as follows:
- It iterates through the discountTable array using a for loop.
- For each entry in the discountTable, it checks if the coupon code provided as the argument matches the coupon code in the current entry (discountTable[i][0]).
- If a match is found, the function returns the discount percentage (discountTable[i][1]) associated with that coupon code.
- If no match is found after iterating through the entire discountTable, the function returns 0, indicating that there is no applicable discount for the provided coupon code.
These functions can be used to calculate the cost of items with discounts based on coupon codes, making them useful for various e-commerce and business scenarios where cost calculations need to consider discounts.

Item | Quantity | Price | Coupon Code | Discount | Total Cost |
Item 1 | 2 | 10 | SALE20 | ||
Item 2 | 3 | 15 | SUMMER | ||

Step 1: Setting up the Spreadsheet
- Create a new Google Sheets document.
- Enter your item details, quantities, prices, and coupon codes in columns A to D starting from row 2.
- Leave cells in columns E and F empty for now.
- Enter the coupon codes and their corresponding discounts in columns H and I.
Step 2: Writing the Google Apps Script Code
- Click on “Extensions” in the top menu, then select “Apps Script”.
- Delete any default code and replace it with the following script:
// Custom formula to calculate the total cost of items with coupon discounts
function CALC_TOTAL_COST(items, quantities, prices, couponCodes, discountTable) {
var totalCost = 0;
for (var i = 0; i < items.length; i++) {
var quantity = quantities[i];
var price = prices[i];
var couponCode = couponCodes[i];
var discount = getDiscount(couponCode, discountTable);
var cost = quantity * price;
cost = cost – (cost * discount);
totalCost += cost;
items[i][5] = cost;
}
return totalCost;
}
// Helper function to get the discount from the discount table
function getDiscount(couponCode, discountTable) {
for (var i = 0; i < discountTable.length; i++) {
if (discountTable[i] === couponCode) {
return discountTable[i][1];
}
}
return 0; // Default to no discount if coupon code not found
}
Step 3: Using the Custom Formula in Google Sheets
- Go back to your Google Sheets document.
- In cell F2, enter the following formula:
=CALC_TOTAL_COST(A2:A, B2:B, C2:C, D2:D, H2:I)
Explanation of the Code:
- The function CALC_TOTAL_COST calculates the total cost of items in a shopping cart, considering discounts based on a coupon code.
- It takes five parameters: items, quantities, prices, couponCodes, and discountTable.
- items: The range of cells containing the item names.
- quantities: The range of cells containing the quantities for each item.
- prices: The range of cells containing the prices for each item.
- couponCodes: The range of cells containing the coupon codes for each item.
- discountTable: The range of cells containing the coupon codes and their corresponding discounts.
- Inside the function, a loop iterates through each item in the shopping cart.
- It calculates the cost of each item and applies the discount based on the coupon code.
- The getDiscount helper function is used to retrieve the discount from the discount table based on the coupon code.
- The calculated cost of each item is stored in column F.
- The function returns the total cost of all items in the shopping cart.
Step 4: Testing the Custom Formula
- Enter item details, quantities, prices, and coupon codes in columns A to D starting from row 2.
- Enter the coupon codes and their corresponding discounts in columns H and I.
- Use the custom formula in cell F2 to calculate the total cost of items in the shopping cart with applicable discounts.
For example, if you have entered the item details and coupon codes as shown in the data table, the calculated total cost in cell F2 should reflect the cost of items with applicable discounts based on the coupon codes.
Remember to enable the “Google Apps Script” extension and use the exact function name (CALC_TOTAL_COST) in your formula.
